Had this mobile control for quite a while but never used it as my garage is to far away from the router and the ECoS but we are working towards it now to establish a connection., I've got 2 choices:

1.)an unused telephone cable (not connected at the moment)
2.) a 2nd router

When its all connected it will allow us to use the Mobile control II and walk freely around the layout and control specific trains etc etc.
I also have the Mobile control I but this gadget just turns itself off without any warning when the battery gets low.
in the next 6 month or so we'll get another ECoS and another Mobile II
